Suppose that the average time spent per day with digital media several years ago was 3 hours and 16 minutes. For last year, a random sample of 20 adults in a certain region spent the numbers of hours per day with digital media given in the accompanying table. Preliminary data analyses indicate that the t-interval procedure can reasonably be applied. Find and interpret a 99% confidence interval for last year's mean time spent per day with digital media by adults of the region. (Note: x = 5.64 hr and s = 2.25 hr.) Click here to view the digital media times. Click here to view page 1 of the t-table. Click here to view page 2 of the t-table. The 99% confidence interval is from hour(s) to hour(s). (Round to two decimal places as needed.)
